Due to an odd quirk of genetics and some unique evolutionary circumstances, two humans who lived at different times in the distant…

  1. If humans have only been on earth for a specific number of years, why can't we estimate the number of years (of more common ancestors) that predate the two samples that you discussed?

  2. Theyre only using y chromosome to trace men… That doesnt mean that a woman doesn't pass on mitochondrial DNA to her sons. And theyre only using mitochondrial DNA to trace women, but that doesnt mean that fathers dont pass half their genome on to their daughters. Just because we have traced the y chromosome and mitochondrial DNA as far back as we can, doesn't mean that we're all descended from one specific couple

  3. This is part of achieving enlightenment. Realizing that all humans, literally, are related to each other. Not just that, but our very atoms were once a part of the universe, before Earth was even a thing.

  4. What then is the value of racists who 😊 discriminate and hate on the basis of race❗❗ like it or not you are the same as any of the rest of us❗❗🔥🔥

  5. If you fail to have at last one biological son and daughter, you will end an unbroken chain going back to the first life to distinguish between male and female sexes. If you fail to have any biological children at all, you will be the first to do so since the beginning of life 4 billion years ago.

  6. The beginning premise is not true. In fact from that explanation it is not sure where all these y-chromosomes converge and if they actually do. The explanation also holds when there are two Y-chromosomes and one half of the males have the one and the other half the other. And those two individuals do not have to be human either.

  7. I wonder how much intersex individuals who are capable of reproduction could throw wrenches into this whole idea if at all!

    Prolly not significantly, but still an interesting thought.

  8. Why does it Reduce to just Two People if Everyone has the Genes. At what Point in Time did Everyone have these Two Ancestoral Genes ?.

    Also this Seems to Assume that Human Population Always Increases with Generations but it's Highly Likely the Human Population Also went Down for Long Periods of Time. ?.

    Also this Presentation Assumes No Circular, No Return Migrations and All Migration Out of Africa No Migration into Africa. They Never went Home, Highly Unlikely. ?.
